# Deposit Liquidity

> Low-level instruction to deposit tokens into a vault and mint LP tokens

# createDepositLiquidityInstruction

Builds a raw instruction to deposit tokens into a Strategy Vault and receive LP tokens in return. The depositor specifies the token mint, the amount to deposit, and a minimum LP output to protect against slippage. Called by depositors who want to add liquidity to the vault.

## Usage

```typescript theme={null}
import { createDepositLiquidityInstruction } from "@exponent-labs/exponent-sdk/client/vaults";
import { PublicKey } from "@solana/web3.js";

const ix = createDepositLiquidityInstruction(
  {
    depositor: wallet.publicKey,
    vault: vaultAddress,
    exponentPrices: exponentPricesPda,
    tokenSrc: depositorTokenAccount,
    entryTokenVault: vaultEntryTokenAccount,
    tokenLpDst: depositorLpTokenAccount,
    mintLp: lpMintAddress,
    tokenProgram: TOKEN_PROGRAM_ID,
    eventAuthority: eventAuthorityPda,
    program: EXPONENT_VAULTS_PROGRAM_ID,
  },
  {
    mint: tokenMintAddress,
    tokenAmountIn: BigInt(1_000_000),
    minLpOut: BigInt(990_000),
  }
);
```
